Very bad service!

For January 2015 i phoned in to confirm my monthly payment, a guy told me over the phone its R499 for the 2mb/s uncapped. I knew its R629.00 per month but in the month of January i had problems with my Internet connection so i thought they reduced the price because i had so much problems. On 12/02/2014 i spoke to Elizma and she told me i have an outstanding balance for last month, a R120 that i owe them. When i told Elizma that a guy told me it was R499 for last month she laughed like i was making it up or lying. I Phoned on 12/02/2015 to hear why my internet was down so she told me they bussy with DNS settings or something like that, so she asked if i received those settings and i told her, \know i never got them". Why am i always the last person to know about changes and why only when i phone i received those settings ? Not that they worked but its principle. Everytime i phone Elizma tells me she will let someone contact me and that also never happens i must always waist my time to contact them. Now i mean is that good service or ****? You tell me."""
